Satellite Imagery Products
GeoEye categorizes its imagery products according to resolution and
positional accuracy, which is an assessment of the closeness of the object's
location in relation to its true position on the Earth's surface. Location error
is defined in relation to a confidence level (i.e., range of error) of 90% (CE90)—meaning
that the object's location is represented on the image, within the stated accuracy,
90% of the time. The CE90 accuracy scale can be related to Root Mean Square Error
(RMSE) as well as the U.S. National Map Accuracy Standards (NMAS).
